Triangulation is a literary category built around the power of three: narratives, perspectives, timelines or forces that intersect, conflict and refract meaning as they converge. Books in this genre set up triadic relationships—three narrators, three versions of an event, or three competing agendas—and use shifting viewpoints, unreliable testimony, and strategic alliances or betrayals to pry open truth, motive and identity. Whether realized as a psychological drama, political thriller, relational study or experimental novel (and echoing the research idea of synthesizing multiple sources in nonfiction), triangulation foregrounds comparison, tension and recalibration: the story’s truth emerges only when the three angles are held against one another and the seams between them are exposed.
